1st generation: em61
used in the first generation nissan leaf, is a stand alone ipsm motor with a theoretical peak power output of a 250kw+.
regarded as nissans "r&d" motor, being the presents of stronger rare earth magents and design. resulting in a slightly higher torque output effeicny than the gen2 em57 motor.
In the stock OEM leaf, the motor was battery and inverter limited to 80kw and made 280Nm of peak torque.
The EM61 made its debut in 2010. It was used only in the first generation Nissan Leaf (ZE0 2010-2012).
2nd generation: em57
The EM57 is an improvement over the first generation. It was first released with the AZE0 Nissan Leaf refresh in 2013.
This motor features a smaller footprint, allowing for 11.7 kg of weight savings in the inverter/motor package. The motor also trades some peak torque for a more efficient power range.
The em57 utilizes a stacking architecture for the power electrons, compared to the isolated nature of the em61 motor.
Nissan has continued to use the em57 motor threw multiple generation of vehicles, resulting in mechanically plug and play OEM inverter upgrades.
inverters currently compatible with the em57 motor:
- gen 2 leaf 80kw inverter
- gen 3 leaf 110kw inverter
- gen 3 leaf 160kw inverter
